What should I do if I see someone who is driving while they are impaired?

How can I prevent impaired driving?

If you think you might be drinking or doing drugs, plan ahead for a safe ride home. This can include getting a ride from a family member or friend who hasn’t been drinking (a designated driver), taking a taxi or taking public transit.

If you are taking medications, it is also a good idea to talk to your doctor or pharmacist about their effects on driving. You should not drive after taking certain medications. Being tired, sick or stressed can also affect your ability to drive safely.

Drinking and Driving Laws

Drinking and driving laws are based on your Blood Alcohol Concentration (BAC). This is the amount of alcohol in your blood. BACs are based on many factors including your gender, weight, how fast you drink and how much you have eaten. The best way to have a safe BAC is not to drink at all.

Blood Alcohol Content (BAC) Limits

For most drivers, driving with a BAC over 0.08 (80 milligrams of alcohol in 100 millilitres of blood) is a criminal offence. You can also be penalized for having a BAC in the “warn range” of between 0.05 and 0.08.

Some drivers, such as those under 21 years old or people without a lot of driving experience must have a zero BAC.
